Helppp

Hey so i'm trying to find a story i've read not long ago but forgot the name and most of the plot.
It's the typical royalty reincarnation/regression shoujo manhua and the mc is a girl that pretends since her childhood to be stupid and ignorant in order to not get killed by her brother ( i think) all the siblings are hunting down each other for the throne or smt. The dad is sick about to die i think. That's all i remember. :')
Not sure, i think it wasnt available on mgg and i had to read somewhere else
